AB  - Indications exist that paramagnetic calcium phosphates may be able to promote regeneration of bone faster than their regular, diamagnetic counterparts. In this study, analyzed was the influence of paramagnetic cobalt-substituted hydroxyapatite nanoparticles on osteoporotic alveolar bone regeneration in rats. Simultaneously, biocompatibility of the material was tested in vitro, on osteoblastic MC3T3-E1 and epithelial Caco-2 cells in culture. The material was shown to be biocompatible and nontoxic when added to epithelial monolayers in vitro, while it caused a substantial decrease in the cell viability as well as deformation of the cytoskeleton and cell morphology when incubated with the osteoblastic cells. In the course of 6 months after the implantation of the material containing different amounts of cobalt, ranging from 5 to 12 wt%, in the osteoporotic alveolar bone of the lower jaw, the following parameters were investigated: histopathological parameters, alkaline phosphatase and alveolar bone density. The best result in terms of osteoporotic bone tissue regeneration was observed for hydroxyapatite nanoparticles with the largest content of cobalt ions. The histological analysis showed a high level of reparatory ability of the nanoparticulate material implanted in the bone defect, paralleled by a corresponding increase in the alveolar bone density. The combined effect of growth factors from autologous plasma admixed to cobalt-substituted hydroxyapatite was furthermore shown to have a crucial effect on the augmented osteoporotic bone regeneration upon the implantation of the biomaterial investigated in this study.

AB  - In recent years, calcium hydroxyapatite (HAp) and its substituents are increasingly used in dentistry and medicine. The influence of nanoparticles Ca / Co-HAp in strengthening weak osteoporotic bone jaw tegmenta was tested in an experimental model. The study was conducted on Wistar soy rats, aged 6-8 weeks. The biomaterial was implanted in the osteoporoticly weakened mandible of these animals. The best results in the strengthening of the lower jaw bone tegmenta were achieved 24 weeks after implantation of hydroxyapatite nanoparticles in which the calcium ion was substituted with 12% of cobalt ions. Histochemical parameters of bone synthesis were in a statistically significant increase. SEM analysis showed a high degree of osteogenetic ability of nano-particulate material implanted in the bone defect.

AB  - Increased life expectancy in developed countries leads to an increase in the number of musculoskeletal disorders, such as osteoporosis, oasteoratritis thus compromising good dental treatment. There are many drug delivery systems based on hydroxyapatite used in bone tissue regeneration. Vitamin D3 is osteodiferentiation factor which regulates bone formation by increasing osteoblast differentiation and bone mineralization. The aim of this study is to examine new multifunctional nanoparticulate system for local delivery of active form of vitamin D3 by biochemical blood marker and histochemical analysis. The research was carried out on female Westar rats, aged 6-8 weeks, which have been implanted biomaterials in the artificial bone defect. Biochemical markers of osteogenesis were statistically significant after only 6 weeks of implantation. ALP activity in bone tissue was showed by histochemical analysis as well as high level reparatory skills. Local realized Vitamin D3 contribute to bone formation by increasing osteoblast differentiation and bone mineralization.

AB  - One of the trends in the treatment of reduced bone density is in oral implantology through the use of new biomaterials with paramagnetic properties. In this in vivo study the effect of Ca /Co-HAp nanoparticles (calcium/cobalt-hydroxiapatite) in the regeneration of the reduced alveolar bone density in experimental animals was examined by analyzing both the biochemical and histochemical markers and through analysis of alveolar bone density. The research was carried out on female Westar rats, aged 6-8 weeks, whom have been implanted nanobiomaterial in reduced alveolar bone density. Good results in regeneration of reduced bone density were achieved in six weeks after implantation of the nanoparticles with paramagnetic properties. Biochemical markers of osteogenesis showed statistically significant rise. Histological analysis revealed high level reparatory skills of the biocomposite implanted in the bone defect, while X-ray analyses evidenced rise of bone density. Implantation of Ca/Co-Hap enables rapid new formation, thus becoming the material of choice for accelerated reduced bone density regeneration.

AB  - Systems for targeted delivery of drugs with high affinity for specific organs, tissues, and cells were introduced at the beginning of the twentieth century. Recently, this concept is attracting much attention. These systems have shown most effective in reducing adverse effects of drugs. In recent years, scientists have created a system of nanoparticles for delivery of vitamin D. Special attention is paid to the role of vitamin D in the division and differentiation of osteoblasts and thus, in its role in osteogenesis. In this regard it was interesting to observe the local effects of the active form of vitamin D3 in osteogenesis, as a part of the system for local delivery. These effects were observed on an experimental model. Three types of nanobiomaterial were implanted in the artificially made defects in rats’ mandibular bone. Six weeks after implantation of hydroxyapatite, hydroxyapatite-coated vitamin D3 and hydroxyapatite nanoparticles coated with vitamin D3 mixed with the polymer, the animals were sacrificed, and the samples of mandibular alveolar bone were taken. The samples were adequately prepared and subjected to histopathological analysis. The best results in regeneration of osteoporotic jaw bone were obtained in the experimental group of animals where the implant was hydroxyapatite-coated vitamin D3 mixed with the polymer. The results show that nanobiomaterials with local delivery of active form of vitamin D3, used in this study, may be materials of the future in the area of weakened jaw bone tissue regeneration.
